Are you running the latest version of jQuery in your WordPress website?
Yesterday, I ran a security scan against my website through Netsparker and found one of the vulnerabilities as “Out-of-date Version (jQuery Migrate)”.
There is known issue with installed version (1.2.1) and it’s best practice to keep your technical stacks up-to-date.
How do you know you are using the latest version of jQuery?
- Use Netsparker to run security scan against your website
- Check Response Header of jquery.js file in HTTP header checker tool
Once you identified that your WordPress website needs upgrading jQuery then here is how you can do it quickly.
Option 1 –wordpress plugin (load jquery locally)
- Login into your WordPress admin console
- Go to Plugins >> Add New
- Search for “jQuery Updater” and install
Option 2 –wordpress plugin (load jquery from Google)
You can also leverage Google Hosted jQuery to keep the latest version. This will not just keep the latest version but also help in loading necessary files faster directly from Google.
“Use Google Libraries” plugin will help you to achieve this.
Once you do the necessary, either you scan your website again or check the HTTP response header to ensure you have the latest version of jQuery.
